Good lookin boy! Sorry to sound like a newb but is that also known as a white knee ? I only ask because i have a sling /juvie sold as a. geniculata or giant white knee and it has the same brown to it .l
@Pernicious Yes, Acanthoscurria geniculata is commonly known as a "Brazilian whiteknee tarantula" or "whitebanded tarantula."
We generally use scientific names here, because it eliminates ambiguity and makes it easier for international users to be on the same page. (People who speak English as a second language may not be familiar with all of the various common names people use, but Acanthoscurria geniculata means the same thing to everyone.)
